flexibility of nickle/chrome/gold plate

[studuff]

I was wondering how the adherence of the above plating would be affected if they were used on something like a coil spring - something that will be flexing a certain amount. Would the plate be likely to crack or flake off?

Thanks - Stuart

Nickle and chrome are fairly hard metals and would likely crack if flexed.

Gold, being softer, is less likely to crack.
